Michigan BIOLOGY 171: Introductory Biology: Ecology and Evolution
BIOLOGY 171 is the first course in Michigan's introductory biology sequence, covering evolution, ecology, and biodiversity, and it's a staple of the pre-med and biology-major first year. It pairs with BIOLOGY 172 (molecular and cellular) to complete the intro bio requirement.

What makes it hard
The volume of material is the challenge. Lecture moves fast and exams test application, not recall, with data-interpretation and experimental-design questions. Students who study by rereading slides get surprised; the exams want you to reason about evolutionary scenarios and ecological data you haven't seen before.
What you'll cover
- • Natural selection and evolutionary mechanisms
- • Population genetics
- • Speciation and phylogenetics
- • Population and community ecology
- • Ecosystems and biodiversity
- • Experimental design and data interpretation
The BIOLOGY 171 study guide
How to study for Michigan BIOLOGY 171, step by step.
- 1
Review each lecture within a day
BIOLOGY 171's challenge is volume, and material you don't consolidate within 24 hours has to be relearned at exam time. A short same-day review of every lecture keeps the load manageable.
- 2
Study by asking what experiment would show it
Exams test application. For every claim in lecture, ask what data or experimental design would support it and what result you'd predict. That's literally the format the questions take.
- 3
Use flashcards for terms, then go beyond them
The terminology (Hardy-Weinberg, clades, trophic levels) needs to be automatic, but recall alone won't pass. Pair flashcard review with scenario questions that force you to apply the concepts to data you haven't seen.
- 4
Work old exams for the data-interpretation style
Past BIOLOGY 171 exams show exactly how Michigan frames evolutionary scenarios and ecological datasets. Practice reasoning through unfamiliar figures rather than rereading slides.

FAQ
Is BIOLOGY 171 hard at Michigan?
It's demanding mainly through volume and exam style. Questions emphasize applying evolutionary and ecological reasoning to new data rather than reciting definitions, so passive studying underperforms. Steady weekly review beats pre-exam cramming decisively here.
Should I take BIOLOGY 171 or 172 first?
Either order works. They're independent halves of the intro sequence. Many students pick based on schedule fit. 171 (ecology and evolution) is often described as more reading- and reasoning-heavy, while 172 is more molecular detail.
How do I study for BIOLOGY 171 exams?
Practice with old exams and concept-application questions, not just flashcards. For each lecture, ask yourself what experiment or data would support the claim being made. That's the format exam questions take.
